Māri (Tamil: மாரி), also known as Mariamman (Tamil: மாரியம்மன்), “Mother Mari”, spelt also Maariamma (Tamil: மாரியம்மா), or simply Amman or Aatha (Tamil: அம்மன், “mother”) is the South Indian Hindu goddess of rain. Māri is closely associated with the Hindu goddesses Parvati and Durga as well as with her North Indian counterpart Shitaladevi. Goddess Mariamman and Goddess Kali are closely associated with each other. Mariamman is a form of Durga who took the form of Kali.

The period of the worship however may be on the preceding nine days (Navaratri) followed by the last day called Vijayadashami(from the sixth to tenth day of the waxing-moon fortnight). Nine aspects of Durga known as Navadurga are meditated upon, one by one during the nine-day festival by devout Shakti worshippers. Durga Puja also includes the worship of Shiva, who is Durga’s consort (Durga is an aspect of Goddess Parvati), in addition to Lakshmi, Saraswati with Ganesha and Kartikeya, who are considered to be Durga’s children.

Worship of mother nature is done, through nine types of plant (called “Kala Bou”), including a plantain (banana) tree, which represent nine divine forms of Goddess Durga. In South India especially, Andhra Pradesh Dussera Navaratri is also celebrated and the goddess is dressed each day as a different devi – Saraswati, Parvati, Lakshmi etc. – for the nine days. The Goddess Durga is worshipped in her peaceful form as Maha Gauri.
